North and South Korea have combined their women's hockey team for the Winter Olympics, but what motive could the two countries have behind the move?

Nusta Carranza Ko is an assistant professor of political science at Ohio Northern University and is of South Korean descent. She said the move is a tactical and humanitarian initiative for both sides. It brings peace, momentarily, for both countries at first glance, and also so that South Korea can focus on its need for tourism. Ko said this is the best outcome given the hostile rhetoric.

"Kim Jong Un is using this approach to also show 'I can come to the table. I can come to the negotiating table'," said Ko. "But in reality, what he's doing with this move is at least showing that he has this other side. That he is willing to have some level of negotiations, he has a little bit of flexibility."
